So you may ask, why aren't these scripts being hosted in the Ubiquity Herd? Well, I've had trouble with those scripts being disabled on / disappearing from my local browser during maintenance windows. Do a [View auto-updated source] on one of the missing ones (the command names won't even be listed on your about:ubiquity page) and you'll get:

// The herd is down for maintenance.

And the herd was down this way for months before Ubiquity 1.3 came out. Perhaps I'll move them over eventually :)
